Got most of the SL_PLAN finished despite some duds and early disruptions. Got several good plasmas for intensity calibration of AXUV and foil bolometers using Ar seeding and spatial calibration using Ar seeded plasma with a large outer gap scan. Piggybacking on to this I was able to get matched RF and gap scan plasmas with and with out the crystal mask for the He-like HIREXSR crystal. The W injections worked out very well and I was able to isolate the spectral lines from W on XEUS and get impurity confinement times using McPherson. The N2 seeded plasmas went OK, but didn't create the strong edge radiation layer I was hoping, even w/o ICRF. Still they're very useful for the N V emission comparison using the Ly-alpha cameras and CXRS and seeing the He-like spectra on XEUS.

Run summary for Friday 2010/02/05 MP534 - Foil/AXUV bolometer calibration in helium (half-day) Session leaders: M. Reinke Physics operator: R. Granetz We got off to a slow start because of several mistakes made in the setup of the gas plenum system, and to a minor problem with the alternator. But by shot 3 we were getting helium plasmas with lots of impurity gas puffing (argon, then nitrogen). We also did a few shots that scanned the outer edge inward, and these worked reasonably well too. At about 11:00 the run was paused for a few minutes to allow Congressman Ed Markey and his party to tour the C-Mod cell and see the tokamak. Scorecard: 14 plasmas 2 dud (due to EF1U problem) 1 fizzle 0 power supply tests 0 no-power MDS shot cycle -------------- Total: 17 shot cycles

Session Leader Comments
Feb 5 2010 09:11:36:997AM	1100205001	Matt Reinke	Dud
Feb 5 2010 09:47:13:713AM	1100205002	Matt Reinke	Shot ran but seems like D2 was the working gas, not He. RF ran well. NEXT: Move on to seeding with Ar. Enable 2.0 psi puff from 0.4-1.2. Add W injection at 1.55 seconds.
Feb 5 2010 10:05:14:737AM	1100205003	Matt Reinke	Good shot, plenty of Ar, W injection large but not a killer. Bolometer signals look great, too. Still some neuts.H-a/Ly. NEXT: Repeat to degas
Feb 5 2010 10:19:31:647AM	1100205004	Matt Reinke	Lost density control, getting nl04~1.5 and huge MARFE. Flash heating to degas the walls, I guess. NEXT: Repeat w/ density control, please. Lower target to nl0=0.8 to try and avoid MARFE.
Feb 5 2010 10:32:53:760AM	1100205005	Matt Reinke	Full length shot. Still density control problems. NEXT: Bob's tweaking gas, but otherwise repeat.
Feb 5 2010 11:03:50:960AM	1100205007	Matt Reinke	Excellent steady density shot. NEXT: Repeat w/ HIREXSR He-like crystal masked
Feb 5 2010 11:24:37:953AM	1100205008	Matt Reinke	Wonderfully reproduced shot! HIREXSR w-line down about 1/2 as expected and the measured ion temperature reduced on w/z but not on Ly-a. Good test of finite crystal effects!!!! NEXT: Repeat after the Gentleman from Massachusetts gets out of the cell.
Feb 5 2010 11:34:03:097AM	1100205009	Matt Reinke	Early disruption. Would like to have another repeat w/ crystal cover but want to move on. NEXT: Load outer gap scan plasma. ICRF off, IMPINJ off, Ar puff from 0.3-0.4.
Feb 5 2010 12:05:07:280PM	1100205010	Matt Reinke	Good outer gap scan on this shot with plenty of Ar. NEXT: Repeat shot with an additional 0.7-0.8 Ar puff.
Feb 5 2010 12:05:23:843PM	1100205011	Matt Reinke	Dud, power supply failure. NEXT: Repeat 010 w/o crystal cover and remove the 0.7-0.8 Ar puff that was supposed to be in 011.
Feb 5 2010 12:16:16:740PM	1100205012	Matt Reinke	Early injection killed shot. NEXT: Try again to get a repeat of 010
Feb 5 2010 12:29:00:743PM	1100205013	Matt Reinke	Good repeat of 010 w/o the crystal cover. NEXT: Repeat 008 w/ N2 puffing. Turn off cryopump, and put 6 psi N2 in B-SIDE-LOWER.
Feb 5 2010 12:47:06:330PM	1100205014	Matt Reinke	Good shot. See N2 in the plasma and residual Ar. Plasma handles the N2 just fine. NEXT: Increase N2 pressure to 10 psi. Decrease ICRF power to 2 MW.
Feb 5 2010 12:58:31:223PM	1100205015	Matt Reinke	Good shot. NEXT: Repeat w/o RF.
Feb 5 2010 01:09:56:680PM	1100205016	Matt Reinke	Ugh, early disruption. NEXT: Last shot, try one more time.
Feb 5 2010 01:23:31:560PM	1100205017	Matt Reinke	Shot disrupted early, looks like an injection, but still got the data I wanted from it.

Physics Operator Comments
Feb 4 2010 10:00:06:840PM		Robert Granetz	Load seg 1 from seg 1 of most recent shot (1100204030). Keep pre-fill pulse at 50+ ms; Cryopump on. Load seg 2 from SEG 4 of 1080411024 (USN, 1 MA, 5.4 T). Update all Bp- and flux-dependent wires. Load nl_04 with nl_04 from most recent shot (valve driver board still not replaced, copy PG3 voltage programming from most recent shot), and program nl_04=1.0e20 m-2. Program PG1 from t=0.3 to 1.2 s, but disable for beginning of run. Load seg 3 from SEG 4 of 1071221002 (ramped RCUR & Ip). Update all Bp- and flux-dependent wires. Load nl_04 with nl_04 from most recent shot (valve driver board still not replaced, copy PG3 voltage programming from most recent shot), and program nl_04=0.7e20 m-2 (same as 1071221002). Program PG1 from t=0.3 to 0.5 s. Save (the night before) as 1100205000 in /home/granetz/pcs_scratch
Feb 5 2010 09:12:01:933AM	1100205001	Robert Granetz	Shot 01 -- Dud, almost no pre-fill gas. The B-top plenum was mistakenly filled to 2 psi only. There's also a minor problem with a gas valve in the alternator house. Next shot: try again
Feb 5 2010 09:31:17:300AM	1100205001	Robert Granetz	After shot 1 the alternator had to spin down. This is causing a delay in starting shot 2.
Feb 5 2010 09:51:45:400AM	1100205002	Robert Granetz	Shot 02 -- Plasma, full length. But the fueling plenum was filled with D2, even though my run setup clearly specified helium. 1.0 MA, 5.46 T, 0.9e20 m-2, USN. Prf=2.9 MW (D+E) Next shot: repeat, but with helium. Also enable the Ar puff (B-side-lower); also tweak Btor; also reduce the P and D feedback on nl_04 to account for helium recycling
Feb 5 2010 10:07:33:283AM	1100205003	Robert Granetz	Shot 03 -- Plasma, nearly full length; disrupted at t=1.69 s during the rampdown. W injection at t=1.55 s. Lots of argon radiated power. Prf=2.9 MW. Next shot: tweak up nl_04 P gain, turn on nl_04 I gain; move W injection to t=1.3 s.
Feb 5 2010 10:21:32:477AM	1100205004	Robert Granetz	Shot 04 -- Plasma, disrupted at t=0.74 s. Large density overshoot (nl_04=1.6e20 m-2), although the fueling valve was not open much. Perhaps it was the argon puff? RF pulse? marfe? Next shot: turn off integral gain on nl_04, decrease nl_04 to 0.8e20 m-2; reduce pre-fill pulse by 3 ms (disruption recovery)
Feb 5 2010 10:35:26:043AM	1100205005	Robert Granetz	Shot 05 -- Plasma, full length. Density control is not good enough. Next shot: adjust PG3 programming, which is going to take a few shots because we don't have the usual chopper feedback circuit, so the valve control is very non-linear; Add 2 ms back to pre-fill
Feb 5 2010 10:47:05:500AM	1100205006	Robert Granetz	Shot 06 -- Plasma, but very short. Lots of hard x-rays. Startup looks okay. Not sure what the problem was. Next shot: no DPCS changes
Feb 5 2010 10:57:42:490AM	1100205007	Robert Granetz	Shot 07 -- Plasma, nearly full length. Density looked pretty good. Startup needs some work. 1.0 MA, 5.4 T, 0.9e20 m-2, USN, Prf=2.9 MW. Next shot: reduce pre-fill by 3 ms
Feb 5 2010 11:11:26:260AM	1100205008	Robert Granetz	Shot 08 -- Plasma, full length. Very similar to previous shot; good density control. 1.0 MA, 5.4 T, 0.9e20 m-2, USN, Prf=2.9 MW. Tungsten injection at t=1.3 s. Lots of argon puffing. Still have early hard x-rays, and the startup still has a slight pause in the early current rampup. Next shot: reduce pre-fill 1 ms
Feb 5 2010 11:26:09:157AM	1100205008	Robert Granetz	We paused the run to let Congressman Ed Markey and his party tour the C-Mod cell.
Feb 5 2010 11:39:06:147AM	1100205009	Robert Granetz	Shot 09 -- Plasma, disrupted at t=0.43 s. I think this was due to an impurity injection. Huge early hard x-ray signal. Next shot: switch to 2nd part of MP, the outer gap scan plasma. Turn on segment 3, which I have preloaded with the desired shot. But reduce the argon puff to 100 ms (was 200 ms), and copy over all the relevant traces for nl_04 (PG3 programming, P, I, D gains) and set nl_04 to 0.7e20 m-2
Feb 5 2010 11:49:56:260AM	1100205010	Robert Granetz	Shot 10 -- Plasma, disrupted at t=1.42 s. This was a limiter discharge which scanned the outer edge inward, and it worked reasonably well. The current is also ramped down to keep q95 nearly constant. Ohmic. DNB fired into plasma, but I_beam was only 0.5 amps. Next shot: add a 2nd argon puff at t=0.7 s for 100 ms.
Feb 5 2010 11:59:42:687AM	1100205011	Robert Granetz	Shot 11 -- Dud. EF1U switch opened way too early. Next shot: try again; remove 2nd argon puff
Feb 5 2010 12:17:15:830PM	1100205012	Robert Granetz	Shot 12 -- Plasma, but it got killed at 22 ms by a big injection. Plasma current got up to 120 kA, so it was not a fizzle. Next shot: try again, no changes
Feb 5 2010 12:29:48:510PM	1100205013	Robert Granetz	Shot 13 -- Plasma, nearly full length. Outer gap scan, just like shot 10. Ohmic. Next shot: reload shot 8 (radiative shot), except switch argon to nitrogen, and turn off cryopump (so decrease the pre-fill to 25 ms). Turn RF back on.
Feb 5 2010 12:44:15:623PM	1100205014	Robert Granetz	Shot 14 -- Plasma, full length. 1.0 MA, 5.4 T, 0.9e20 m-2, USN, Prf=2.9 MW. Tungsten injection at t=1.3 s. Ugly startup. Next shot: reduce pre-fill by 3 ms; increase N2 pressure to 10 psi
Feb 5 2010 12:55:34:753PM	1100205015	Robert Granetz	Shot 15 -- Plasma, full length. Decent shot, but terrible startup. Next shot: repeat, but turn off the ICRF; increase pre-fill by 6 ms
Feb 5 2010 01:07:51:790PM	1100205016	Robert Granetz	Shot 16 -- Fizzle. Bad startup. Next shot: add 4 ms to pre-fill
Feb 5 2010 01:21:13:200PM	1100205017	Robert Granetz	Shot 17 -- Plasma, disrupted at t=0.74 s due to an injection. Startup was much better, but still huge hard x-ray signal End of (half-day) run.
